1. Basic Trigonometric Ratios

These are defined in relation to a right-angled triangle:

$\sin \theta = \frac{\text{Opposite side}}{\text{Hypotenuse}}$

$\cos \theta = \frac{\text{Adjacent side}}{\text{Hypotenuse}}$

$\tan \theta = \frac{\text{Opposite side}}{\text{Adjacent side}}$

$\csc \theta = \frac{\text{Hypotenuse}}{\text{Opposite side}}$

$\sec \theta = \frac{\text{Hypotenuse}}{\text{Adjacent side}}$

$\cot \theta = \frac{\text{Adjacent side}}{\text{Opposite side}}$

2. Pythagorean Identities

$\sin^2 \theta + \cos^2 \theta = 1$

$1 + \tan^2 \theta = \sec^2 \theta$

$1 + \cot^2 \theta = \csc^2 \theta$

Shortcut Formulas

We have provided below the shortcut formulae related to average speeds, boat stream, circular tracks, meeting point, to make your calculations faster in the CAT 2025 exam.

1. Average Speed Formulas

Case 1: Equal distances, different speeds
If the distance covered in each stage of a journey is the same, but speeds are different, the average speed is the harmonic mean:

$ \text{Average Speed} = \frac{2 s_1 s_2}{s_1 + s_2} $

Example:
Distance from A to B and B to C is the same. Speeds: $s_1$ and $s_2$. Then:

$ \text{Average Speed} = \frac{2 s_1 s_2}{s_1 + s_2} $

Case 2: Equal time, different speeds
If the time taken in each stage is the same but speeds differ, the average speed is the arithmetic mean:

$ \text{Average Speed} = \frac{s_1 + s_2}{2} $

2. Circular Track – Same Direction

If two people start from the same point on a circular track of length $D$ km with speeds $a$ & $b$ kmph in the same direction:

  1. Time for first meeting:

$ t_{\text{first}} = \frac{D}{|a-b|} $

  1. Time to meet again at the starting point:

$ \text{Meeting points} = |x - y| $

Where $x:y$ is the simplified ratio of speeds.
Example: If $a = 12$ kmph, $b = 9$ kmph → $x:y = 12:9 = 4:3$ → $x=4$, $y=3$.

3. Circular Track – Opposite Direction

If two people start from the same point in opposite directions:

  1. Time for first meeting:

$ t_{\text{first}} = \frac{D}{a+b} $

  1. Time to meet again at the starting point:

$ t_{\text{start}} = \text{LCM}\left(\frac{D}{a}, \frac{D}{b}\right) $

  1. Number of distinct meeting points:

$ \text{Meeting points} = |x + y| $

Where $x:y$ is the simplified ratio of speeds.

4. Meeting Point Between Two Opposite Travellers

If a person $P$ starts from $A$ towards $B$, and $Q$ starts from $B$ towards $A$, and they meet after time $t$:

$ t = x \cdot y $

Where:

  • $x$ = time taken by $P$ to reach $B$ after meeting

  • $y$ = time taken by $Q$ to reach $A$ after meeting

5. Boats and Streams

If the speed of the boat downstream is $u$ kmph and upstream is $v$ kmph:

  • Speed of boat in still water:

$ \text{Boat speed} = \frac{u+v}{2} \text{ kmph} $

  • Rate of stream:

$ \text{Stream speed} = \frac{u-v}{2} \text{ kmph} $

Geometry

The Geometry section is the lengthiest section in the Quantitative Aptitude Section which has lots of properties and formulas. Following are 50+ Important Formulas for CAT Preparation of this section which are given in this CAT Formula Sheet:

1. Triangles:

Properties of Triangles:

The sum of all interior angles in a triangle is $180^\circ$ and the sum of all exterior angles is $360^\circ$.

The sum of any two sides is always greater than the third one and the difference of any two sides is less than the third one.

Let $a, b, c$ be the sides of a triangle, then

$|b-c| < a < b+c$

In a scalene triangle the greatest side is always greater than one-third of the perimeter and less than half of the perimeter.

Let $a, b, c$ be the sides of the triangle and $a$ be the greatest side. Let the perimeter be $P$. Then

$\dfrac{P}{3} < a < \dfrac{P}{2}$

Example: In a scalene triangle $ABC$, the perimeter is $24$ cm and all sides are integers.

Let $a, b, c$ be sides of the triangle with $a$ the greatest side. Then

$\dfrac{24}{3} < a < \dfrac{24}{2}$

$8 < a < 12$

So possible values are $9, 10, 11$ cm.

For $a, b, c$ sides of a triangle and $a$ the greatest side:

If $a^2 < b^2 + c^2$, then the triangle is acute angled.

If $a^2 = b^2 + c^2$, then the triangle is right angled (Pythagoras theorem).

If $a^2 > b^2 + c^2$, then the triangle is obtuse angled.

(Here $D$ is the midpoint of side $AC$, so $AD = DC$)

Mid point of triangle

Midpoint of a triangle

  • Length of the Median –
    BD = $\frac12 \sqrt{2(AB^2+BC^2)−AC^2}$

  • 3× (Sum of squares of sides) =4× (Sum of squares of medians), that is,
    $3(a^2+b^2+c^2)=4({M_a}^2+{M_b}^2+{M_c}^2)$
    where a,b, and c are the sides of the triangle and Ma, Mb, and Mc are the medians.

  • In a right-angled triangle, Median of Hypotenuse = Half of Hypotenuse
    That is,
    CD = AB/2

median of hypotenuse

Median of hypotenuse

If all the medians are drawn in the triangle, then the 6 small triangles are generated in the triangle, which are equal in the Area.

Area of Triangle:

Heron’s Formula

If all sides of a triangle are given. Let $a, b, c$ be the sides of the triangle –

Area $= \sqrt{s(s-a)(s-b)(s-c)}$ where $s = \dfrac{a+b+c}{2}$ is the semiperimeter.

If two sides and the included angle are given –

Area $= \dfrac{1}{2} \times \text{(Product of given sides)} \times \sin(\text{included angle})$

Area $= \dfrac{1}{2} \times a \times b \times \sin C$

(Example: sides $a, b$ and included angle $C$ are given)

If a side and its respective altitude (perpendicular drawn from the opposite vertex) is given, then –

Area of the triangle $= \dfrac{1}{2} \times \text{Base} \times \text{Height (Altitude)}$

Shortcut Formulas

Area of an equilateral triangle = $ \frac{\sqrt{3}}{4} a^2 $

Height (Altitude) of an equilateral triangle = $ \frac{\sqrt{3}}{2} a $

Area of a triangle = $ r \times s $ (where $r$ is the inradius and $s$ is the semiperimeter)

Algebra

The Algebra section is a critical part of the Quantitative Aptitude section in the CAT exam. Below are over 50 important formulas for CAT preparation in this section, which are provided in this comprehensive CAT Formula Sheet:

1. Quadratic Equations

General form:
$ ax^2 + bx + c = 0 $

Roots of the equation (Shreedhara Acharya's Formula):
$ x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} $

Sum of roots:
$ \text{Sum} = -\frac{b}{a} $

Product of roots:
$ \text{Product} = \frac{c}{a} $

Discriminant:
$ D = b^2 - 4ac $

  • If $D > 0$, roots are real and distinct

    • Perfect square $D$ → roots are rational (e.g., $x=1,6$)

    • Non-perfect square $D$ → roots are irrational/conjugate surds (e.g., $x = 3 - \sqrt{5}, 3 + \sqrt{5}$)

  • If $D = 0$, roots are real and equal

  • If $D < 0$, roots are imaginary and distinct

Vertex (Maximum/Minimum values):

  • For $y = ax^2 + bx + c$, $a>0$ (Minimum):
    $ x = -\frac{b}{2a}, \quad y_{\text{min}} = -\frac{D}{4a} $

  • For $y = ax^2 + bx + c$, $a<0$ (Maximum):
    $ x = -\frac{b}{2a}, \quad y_{\text{max}} = -\frac{D}{4a} $

Quadratic equation from roots $a$ and $b$:
$ x^2 - Sx + P = 0 $, where $ S = a+b $, $ P = ab $
Or equivalently:
$ x^2 - (a+b)x + ab = 0 $

Progression & Series

Arithmetic Progression (A.P.)

If a is the first term and d is the common difference then the Arithmetic Progression (A.P.). can be written as-

  • a, a+d, a+2d, a+3d, …

Let $a =$ first term

$d =$ common difference

$n$ = number of terms

Nth term of the A.P. –

$T_n = a + (n-1)d$

Sum of the first $n$ terms of the A.P. $(S_n)$ = Average of all the terms $\times$ number of terms $(n)$.

The average of the terms can be found easily:

If the number of terms is odd, then the middle term will be the average.

Example: $2, 5, 8, 11, 14$ are terms of the A.P., then the middle term $8$ is the average.

So, $S_n = \text{average} \times n = 8 \times 5 = 40$.

If the number of terms is even, then the average of the middle two terms will be the average of the A.P.

Formula for sum of $n$ terms:

$S_n = \dfrac{n}{2} \big[ 2a + (n-1)d \big]$

Shortcut Formulae

$S_n = \dfrac{n}{2}(a+l)$ (where $a =$ first term, $l =$ last term, $n =$ number of terms)

$n = \dfrac{l-a}{d}+1$ (number of terms in A.P.)

Geometric Progression (G.P.)

If $a$ is the first term and $r$ is the common ratio, then the G.P. can be written as: $a, ar, ar^2, ar^3, \dots$

Nth term of the G.P.: $T_n = a \cdot r^{n-1}$

Sum of the first $n$ terms:

If $|r| < 1$: $S_n = a \cdot \dfrac{1-r^n}{1-r}$

If $r > 1$: $S_n = a \cdot \dfrac{r^n-1}{r-1}$

Sum of infinite terms of the G.P. (if $|r|<1$): $S_\infty = \dfrac{a}{1-r}$

Where: $a =$ first term, $r =$ common ratio, $n =$ number of terms

$|r|<1$ ensures the series converges.

Shortcut Formulas

If there are odd no. of terms in a G.P., then the product of all terms are equal to the nth power of the middle term.

e.g. 2,6,18,54,162 are the terms of a G.P.

Then the products of all the terms = 185

Harmonic Progression (H.P.)

If a,b,c are in A.P., then $\frac{1}{a},\frac{1}{b},\frac{1}{c}$ are in Harmonic Progression (H.P.).

n-th term of the H.P.=$\frac{1}{n}$-th term of the corresponding A.P.

Series

Sum of first $n$ natural numbers:
$ 1 + 2 + 3 + \cdots + n = \frac{n(n+1)}{2} $

Sum of squares of first $n$ natural numbers:
$ 1^2 + 2^2 + 3^2 + \cdots + n^2 = \frac{n(n+1)(2n+1)}{6} $

Sum of cubes of first $n$ natural numbers:
$ 1^3 + 2^3 + 3^3 + \cdots + n^3 = \left(\frac{n(n+1)}{2}\right)^2 $

Sum of first $n$ odd numbers:
$ 1 + 3 + 5 + \cdots + (2n-1) = n^2 $

Sum of squares of first $n$ even numbers:
$ 2^2 + 4^2 + 6^2 + \cdots + (2n)^2 = \frac{2n(n+1)(2n+1)}{3} $

Sum of squares of first $n$ odd numbers:
$ 1^2 + 3^2 + 5^2 + \cdots + (2n-1)^2 = \frac{n(2n+1)(2n-1)}{3} $

Indices & Surds

Product Rule:
$ a^m \cdot a^n = a^{m+n} $

Quotient Rule:
$ \frac{a^m}{a^n} = a^{m-n} $

Power of a Power:
$ (a^m)^n = a^{mn} $

Power of a Product:

Hello,

With 802 marks in TS Inter and ST category, you have a fair chance of getting admission in BPT (Bachelor of Physiotherapy) in some private colleges through state counselling.

However, for government colleges, the cutoff may be slightly higher, so keep options open for management quota or allied health colleges too.

Hope you understand.


Hey,

You already have a strong profile with the score of 58% in Class 10, 74% in Class 12, and 80% in graduation, but admission in IIT Bombay, Shailesh J Mehta School of Management is quite competitive, especially if you are in general category because the cutoff for general goes to 98.5-99%. Your CAT percentage is impressive but your 10th marks might reduce your score during the shortlisting process. If you perform well in Written Ability Test and Personal Interview, and present your commerce background you still stand a fair chance. But it would also be wise if you have some backups like MDI Gurugram, IMT Ghaziabad, IMI Delhi, where your marks and profile will fit well in their selection range.

The three key formulas that can solve almost all Profit & Loss problems are:

  1. Profit/Loss % = (Profit or Loss / Cost Price) × 100%, where CP is the cost price.

  2. Discount % = (Discount / Marked Price) × 100%, where MP is the marked price.

  3. Mark up % = (Mark up Value / Cost Price) × 100%, where CP is the cost price.


These formulas can be adapted for problems involving discounts, marked price, or successive gains/losses.
